Abstract: A method for use in the construction of a color display screen using deposition of a plurality of electroluminescent materials onto a substrate bearing said screen. The method comprises the forming operations a), b), and c) in any sequence: a) forming on the substrate a first screening pattern of deposition sites covered with a first material selectively strippable by a first agent; b) forming on the substrate a second pattern of deposition sites covered with a second material strippable by a second agent; and c) forming on the substrate a matrix surrounding the first and second patterns of deposition sites. The method includes thereafter performing a first stripping of the first material with the first agent to reveal first deposition sites within the matrix and performing a first depositing of a first electroluminescent material within the first revealed deposition sites. Following the first stripping and depositing, the second material is stripped with the second agent to reveal second deposition sites within the matrix and a second electroluminescent material is deposited within the second revealed deposition sites. By the practice of the disclosed method the forming operations are segregated from the electroluminescent material depositing operations.

Abstract: An ATV system (16, 18, 20) encodes variable length elementary streams of data into a multilevel symbol signal comprising a plurality of multiplexed fixed length data packets without sync information. The fixed length data packets are arranged in fields of repetitive data segments, each of which includes a data segment sync and each field of which includes a field sync. The fields of data segments are transmitted as suppressed carrier VSB modulation (28). In an ATV receiver, the data segment sync is used to generate a timing signal that identifies the beginning of each fixed length data packet. In one embodiment, a packet sync signal is inserted into each recovered fixed length data packet for recovering the elementary streams of data. In another embodiment, recovery of the elementary streams of data is accomplished without inserting a packet sync signal.

Abstract: An AGC circuit for a digital receiver that receives a digital television signal or the like, including a pilot, and formatted in a plurality of repetitive data segments, each data segment comprising a fixed number of multilevel symbols occurring at a constant symbol rate. The multilevel symbols are converted to corresponding digital values and the pilot (represented by a DC offset) is removed from the digital values. Every fourth symbol is sampled and the samples are accumulated and divided to derive an average symbol value. The average symbol value is compared with a reference average symbol value and the result of the comparison is an AGC potential that controls the tuner and IF gains. A cable/terrestrial input alters the sampling for cable signals to compensate for high level sweep testing in cable systems.

Abstract: A convolutional interleaver or deinterleaver comprises an address signal generator for repeatedly generating [(B-1)N/2] + 1 sequences of address signals, where B is a desired interleave depth and N is a value equal to or greater than the number of data bytes in an R-S block of the data stream. Each of the sequences corresponds to a respective row of a B column matrix, the first column of which comprises [(B-1)N/2] + 1 consecutively numbered values. Each remaining column comprises the preceding column rotated by an integer multiple of N/B. The address signals are applied to a memory having [(B-1)N/2] + 1 storage locations for reading the data stored at the address memory location and then writing the current data byte to the same memory location.

Abstract: A frame of compressed video data is formatted for transmission into a plurality of data segments, a first group of which are encoded in the form of a plurality of four-level symbols and a second group of which are encoded in the form of a plurality of two-level symbols for providing improved noise performance. The partition between the first and second groups of data segments may be established on a fixed basis, a variable basis dependent upon the effective level of compression, or a combination of both. Preferably, the two levels of the second group comprise a subset of the four levels of the first group.

Abstract: Process and apparatus are disclosed for use in the manufacture of a color cathode ray tube having a shadow mask with a central pattern of apertures mounted in tension on a transparent flat front panel. The mask aperture pattern is registered with a cathodoluminescent screen pattern of corresponding geometry and position on an inner surface of the panel. The shadow masks and front panels are respectively interchangeable. Signals are developed which are indicative of the positions of a mechanically stretched mask aperture pattern and an associated front panel screen pattern relative to a reference or to each other. Responsive to such signals, there is effected a relative positioning of the mask and screen until registration between the patterns is achieved.

Abstract: An improved cataphoretic process is disclosed for use in the manufacture of a color cathode ray tube. The process provides for depositing in sequence on the tube screening surface at least two separate patterns of phosphor elements, with each pattern of elements capable of emitting light of a different color when excited. The process according to the invention comprises first depositing an electrically conductive coating over the screening surface for use as an electrode during each deposition operation. Second, an electrically insulative barrier is deposited over the conductive coating. Portions of the barrier are removed selectively and sequentially for controlling patterned, sequenced cataphoretic access to the electrically conductive coating.

Abstract: A hybrid television signal of less transmission power or better signal to noise performance is made up by removing low frequency analog components from the video signal (20, 24, 26, 32), digitizing them (26) and sending them as data in non-active video portions of the transmitted signal (30, 22). A two step hybridization process, with the first step removing the line averaged value of the video components of the video signal (20, 24, 26, 32) and the second step removing the remainder of the video components under 200 KHz (20', 26', 32', 37, 39), is described. Temporal filtering, signal pre-emphasis, compression, dispersal and double sideband suppressed carrier modulation about a centered carrier are disclosed for reducing peak signal amplitudes and for minimizing co-channel interference to and from NTSC signals. In an FM implementation, the benefits of the hybrid signal are realized as a reduction in bandwith and consequent improved noise performance. The hybrid signal system is uniquely adapted to a high definition television signal in a limited frequency channel.
